Brief Summary
Removal and prevention of formation of dental plaque biofilms is one of the current hygiene regimen to prevent, reduce or even reverse the gingival and periodontal disease condition. In such endeavors of mechanical plaque removal, tooth-brushing and use of dental floss play an important role. Gomes et al have presented a modification in the use of knotted floss in wider embrasure areas. The modification in the dental floss has been done so as to increase the effective width of the floss. The purpose of this study is to compare the reduction of the clinical signs of plaque accumulation, gingival inflammation and gingival trauma in the area the knotted floss technique has been utilized versus the area where conventional flossing has been utilized in Type I gingival embrasures. Patients' acceptability of the knotted flossing technique will also be evaluated. This study is part of a larger study protocol involving different sample groups comparing the knotted floss technique with conventional dental flossing, use of interdental brushes and unitufted brushes in type II and type III embrasures as well.

Outcome Measures
Primary Outcomes (4)
Rustogi modification of Navy Plaque Index - 6weeks
Rustogi modification of Navy Plaque Index will be assessed at 6-weeks for all subjects in Group A Phase 1, Group B Phase 1, Group A Phase 2, and Group B Phase 2
6 weeks
Lobene's Modified Gingival Index - 6weeks
Lobene's Modified Gingival Index will be assessed at 6-weeks for all subjects in Group A Phase 1, Group B Phase 1, Group A Phase 2, and Group B Phase 2
6 weeks
Barnett's Modified Papillary Bleeding Index - 6weeks
Barnett's Modified Papillary Bleeding Index will be assessed at 6-weeks for all subjects in Group A Phase 1, Group B Phase 1, Group A Phase 2, and Group B Phase 2
6 weeks
Gingival Trauma Index (as described by Carter-Hanson et al 1996)- 6weeks
Gingival Trauma will be assessed at 6-weeks for all subjects in Group A Phase 1, Group B Phase 1, Group A Phase 2, and Group B Phase 2. The Gingival Trauma induced by improper flossing will be assessed by the technique described by Carter-Hanson et al 1996. All interdental areas of the facial and lingual surfaces of the gingiva will be examined for gingival lacerations and indentations, using a mouth mirror, light, and after gently air-drying the gingiva. A score of one (1) will be given to facial and lingual surface separately when floss trauma is identified as a demarcation line or laceration. A score of zero (0) will be recorded if no such trauma is present. The Gingival Trauma Index score per subject will be obtained by totalling all scores and dividing by number of sites examined.

Study Arms (4)
Group A Phase 1
NO INTERVENTION50% of sample are randomly assigned to Group A and are to utilise conventional flossing technique in the first phase of 6-weeks
Group B Phase 1
ACTIVE COMPARATOR50% of sample are randomly assigned to Group B and are to utilise knotted floss technique in the phase 1 of 6-weeks
Group A Phase 2
ACTIVE COMPARATORAfter a washout period of 2 weeks, those from Group A will use the knotted floss technique for a period of 6 weeks.
Group B Phase 2
NO INTERVENTIONAfter a washout period of 2 weeks, those from Group B will use the conventional floss technique for a period of 6 weeks.
Interventions
The subjects use the knotted floss technique. In this modification of conventional flossing technique, a knot is tied in the floss at any distance in the middle third of the floss length. The floss is inserted past the interdental contact point by the conventional finger flossing technique in the non-knotted area and then during the 'to and fro movement' on the tooth surface cervical to contact point, the knotted area is engaged through the embrasure (Gomes et al 2016)

- full mouth Gingival Index ≥ 1.0 (Loe and Silness 1963)
- good general health,
- have all teeth present in quadrant being tested and opposing quadrant
- be available for a 14 week study period,

- habit of unilateral mastication for ≥2 months,
- medical history of diabetes mellitus, hepatitis, pregnancy or requiring any antibiotic prophylaxis,
- having drug history in preceding two months of use of antibiotics, hormonal supplements, steroids, non steroidal anti-inflammatory medications, oral contraceptives or any drug that influence gingival tissue,
- taking part in any other clinical or drug trial including taking part in other study groups related to the evaluation of knotted floss technique,
